My red-node is run via docker.  
Then I see this addon: [node-red-contrib-zigbee2mqtt (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-zigbee2mqtt)

- "npm install" is certainly not something I can do in shell .. so where does this command go?

You are better off just using standard MTTQ nodes

My FlexDash docs have quite an extensive how-to for docker. Obviously it's geared towards FlexDash but it's really all about installing packages. But it may be more complexity than you want to deal with... [Docker - FlexDash](https://flexdash.github.io/docs/quick-start/docker/)

A guide for what in particular?

If you mean information about mqtt then see this tutorial [MQTT Essentials - All Core Concepts Explained](https://www.hivemq.com/mqtt-essentials/)

If you mean specifically about using it with zigbee2mqtt then the best thing to do is to install mqttexplorer on a pc on your network and then you can look to see what mqtt topics your devices use so you can easily access then from node red.

First off, you need to open a shell on the container:

> docker exec -it name\_of\_node-red\_docker /bin/bash

Then, from within the running container, you go to the user dir you mapped when the container was launched, typically `/data`  
Inside you will have a node\_modules directory, you cd into it, and run:

> npm i node-red-contrib-zigbee2mqtt
